Possibly, but due to the heightened level of security for public works in the US since 9/11, it is unlikely that such would be available to the general public.
The two basic categories of transmission are:High voltage transmission andLow voltage transmission.
The highest transmission voltage in the Western Interconnection (2011) is 500kv.
the highest transmission volatage in India is 765kV ac. The highest voltage in the case of DC transmission is +/- 600 kV.
Using a higher voltage reduces power losses during transmission.
its because of transformers . they work with pulse
the inductive load which is generally use in high voltage transmission line known as transformer. the transformer transform the high voltage to low voltage.

The main advantage is that it's very easy to step alternating current up or down in voltage by the use of a transformer. High voltage is preferred for long distance transmission because it cuts transmission loss.
750kv
Voltage is stepped up during transmission to reduce the power loss during transmission due to resistance. Power is a product of Voltage*Current, and losses due to resistance are directly proportional to the square of the current. Now when we increase the voltage , keeping the power constant, the subsequent current reduces.. thus in turn reducing the transmission losses.
Transmission and distribution voltages are normally expressed in terms of line voltages, so the answer is that the figure you quote is a line voltage. Incidentally, do you really mean 230 megavolts for a transmission voltage?? And the symbol of kilovolt is 'kV', not 'kv'.
Transmission Line Charging To initially charge the transmission line, the generator voltage stably controlled from 30% of the rated voltage to 110% of the rated voltage by using AVR. The change-over switch (43CH) for initial transmission line charging is mounted on the operator's desk in the main control room.This Voltage Changes are required because of the Stray capacitance effect at the charging and boosts the Voltage at the other end and the inductance of the line drops the Voltage soon after charging
